Nvidia graphics card unplugged (?) after windows update

Hi, I have a problem. My graphics card which is an Nvidia GTX 1660 Ti is listed by the system as unplugged after I had downloaded and installed the newest windows update (KB4515384) which comes with NET. framework update KB4514359 and Security Update for Adobe Flash Player KB4516115. I did not do anything to the physical card, but the system did not detect it and said that I have to re-plug the card. Can anybody help me? I tried to remove all instances of the card by uninstalling, but I can't seem to get it back.
Hi Jason. I'm Greg, an installation specialist, 10 year Windows MVP, and Volunteer Guardian Moderator here to help you.

1) Can you physically access the card to check it's seated tightly and no cable is detached?

Do you have an onboard GPU chip in addition to the card? Can you try changing between these in BIOS/UEFI Setup? If there's no other GPU then the error is likely false. What is the full error text and number?

2) Update the Display driver from the PC or Display adapter maker's Support Downloads web page for your exact model number, HP Serial Number or Dell Service Tag - from the sticker on the PC.

While there check also for newer chipset, BIOS/UEFI firmware (very important), network, sound, USB3 and other drivers, comparing to the ones presently installed in Device Manager reached by right clicking the Start Menu.

if this doesn't give you the latest or ideal driver for what you need, compare it to the driver offered by the Intel driver update Utility here: http://www.intel.com/content/www/us/en/support/...
or the Nvidia Update utility here: http://www.nvidia.com/Download/Scan.aspx?lang=e...
or the AMD autodect utility here: http://support.amd.com/us/gpudownload/windows/P...

For Display issues one fix that is working is to Roll back or Uninstall the Driver on the Display Device > Driver tab, restart PC to reinstall driver.

You can also try older drivers in Device Manager > Display device > Driver tab > Update Driver > Browse > Let Me Pick.

Then you will know you've tried everything in addition to Windows Update drivers.

3) If this was caused by Windows Update(s) then you can check which were installed at Settings>Update & Security>Windows Update under Update History, then uninstall them from the link there, and immediately check for these again and hide with the Hide Updates tool explained here: https://www.howtogeek.com/223864/how-to-uninsta...

You can also use System Restore to get before the problem began, then check for Updates with the Hide Update tool and hide them: https://www.windowscentral.com/how-use-system-r...

4) If nothing else helps you can run a Repair Install by installing the Media Creation Tool and choosing from it to Upgrade Now. This reinstalls Windows in about an hour while saving your files, apps and most settings, solves many problems while also bringing it up to the latest version 1903 which you need anyway and by the most stable method. http://windows.microsoft.com/en-us/windows-10/m....

I hope this helps. Feel free to ask back any questions and keep me posted. If you will wait to rate my post, I will keep working with you until it's resolved.
